Q1. Health official worldwide are concerned by the resurgence of diseases caused by bacteria that are resistant to standard antibiotics. For example, antibiotics resistant bacteria are now causing an epidemic of TB. Drugs can relieve symptoms in a few weeks, except it takes much longer to halt the infection, and patients are likely to discontinue treatment while bacteria are still present. Why can prakaryotes quickly re infect a patient if they are not wiped out? How may this result in the evolution of drug resistant pathogens?
